Tech tips and tricks from the world of network traffic and security monitoring

Over the past year, we have worked with several customers, both paying and those running the 3-day rolling window version, and found most of them asking us for custom metering. We have over 160 network metrics out of the box, with several mechanisms to derive your own. Still users want to add in their own that doesnt fit in anywhere else. Some requests;

The Lua API

LUA is a very popular small but functional, fast and threadsafe language. We have embedded Lua into the Trisul core, which is written in C/C++. You can write Lua scripts that plug into key processing logic within the Trisul engine. With these scripts you can create your own counter groups, log activity, take action such as generate SNMP traps, and much more.
